    Well, you've certainly got it straight.  I think if I was dealing with
ferrets in a country where neither was approved, I would probably go with
Fromm-D, because there are less reactions (but remember, you may still see
some.) That would answer the "safer" part of your question.
 
    As far as effective - we have no knowledge of Fromm-D effectiveness in
protecting ferrets from distemper.  Fervac-D has been tested in ferrets and
approved by the USDA.  Currently, I have some questions in my mind about
Fervac's actual effectiveness, but certainly it has the better track record.
